B-cell lymphoma of the appendix: A case report and review of literature

Appendicular tumors are rare, and lymphoma of the appendix is rarer. A 50-year-old female patient presented with vague abdominal discomfort and lump in the right iliac fossa. The diagnosis of diffuse large B-cell lymphoma was made after laparotomy and histopathological examination (HPE) supported by immunohistochemistry study. For appendicular neoplasms diagnosed postoperatively, including lymphoma, a meticulous grossing and HPE cannot be over emphasized. In case of wall thickening of >2.50-3 cm detected by the computed tomogram scan, the possibility of a neoplasm or lymphoma in particular should be included as the differential diagnosis irrespective of the clinical presentation.
